Photocatalytic performance of dual Z-scheme CoFe2O4/α-Fe2O3/Co3O4 ternary heterojunction composite synthesized by Pechini method

This work presents the synthesis of a dual Z-scheme CoFe2O4/α-Fe2O3/Co3O4 ternary heterojunction composite (THC), as well as CoFe2O4 (CFO) nanoparticles (NPs) by the Pechini method and their solar-driven photocatalytic performance for the degradation of methylene blue (MB) dye. FT-IR spectroscopy, X-ray diffraction analysis, and Raman spectroscopy were used to confirm the presence of the respective phases in the THC and CFO NPs. Morphology analysis revealed that the THC consisted of disk-shaped and octahedron-shaped particles, while the CFO NPs comprised octahedral and icosahedral particles. After 120 min of sunlight irradiation, the THC system demonstrated superior photocatalytic performance with degradation efficiencies of 68.7 %, 82.3 %, and 88.5 % in aqueous media containing 20, 10, and 5 mg/L of MB, respectively. The enhanced photocatalytic performance of THC is attributed to both α-Fe2O3 and Co3O4 acting as electron mediators in a dual Z-scheme heterojunction mechanism. Besides, the THC demonstrated to have higher first-order kinetics constants than CFO NPs and excellent stability and reusability over four cycles. Finally, the experiments of radical scavengers demonstrated that the main active species for decomposing MB in this system were ·OH and ·O2− active radicals.

Facile Fabrication of ZnO Nanorods with Extremely Strong Photocatalytic Performance and Antibacterial Activity

Development of nanomaterials with strong antibacterial action and highly enhanced photocatalytic activity for water purification is of immense interest. ZnO nanorods, with extremely enhanced solar-driven photocatalytic performance and good antibacterial activity, have been fabricated by facile chemical route. The structural properties of the nanomaterial were thoroughly characterized by SEM, TEM, EDX, HRTEM, STEM-HAADF, elemental profiling, XRD and Raman spectroscopy, while the optical and photocatalytic properties were studied by UV-vis absorption spectroscopy. TEM and FESEM showed nanorods with average width and length as 80[Formula: see text]nm and 178[Formula: see text]nm. XRD showed wurtzite ZnO with 27[Formula: see text]nm crystallite size. PL analysis of ZnO nanorods showed peaks at 415[Formula: see text]nm, 439[Formula: see text]nm, 499[Formula: see text]nm and 561[Formula: see text]nm. The fabricated ZnO nanorods exhibited extremely enhanced photocatalytic performance with very high rate constant of 0.201[Formula: see text]min[Formula: see text] for degradation of organic pollutant MB in water under only 15[Formula: see text]min of solar exposure. ZnO nanorods completely inhibited growth of Bacillus oceanisediminis and Escherichia coli at 500[Formula: see text][Formula: see text]g/mL and 700[Formula: see text][Formula: see text]g/mL, respectively. The origin of antibacterial behavior of ZnO nanorods against B. oceanisediminis and E. coli has been investigated using histidine for scavenging ROS, morphological change by SEM and agarose gel electrophoresis. Our results showed that ROS-induced oxidative stress damages cell wall, evident from SEM, and leads to fragmentation of DNA both of which contribute to the antibacterial action of ZnO nanorods. The tentative mechanism of extremely strong photodegradation performance of ZnO nanorods has also been proposed.

Highly efficient and recyclable quaternary Ag/Ag3PO4–BiOBr–C3N4 composite fabrication for efficient solar-driven photocatalytic performance for anionic pollutant in an aqueous medium and mechanism insights

A simple chemical precipitation route to synthesize the quaternary composite under mild conditions is reported. The quaternary composite photocatalyst Ag/Ag3PO4–BiOBr–C3N4-1 band gap was tuned to 0.56 eV by varying the amount of C3N4 for efficient photocatalytic performance. The as-prepared photocatalysts were characterized by XRD, XPS, TEM, EDAX, BET, EIS, and UV–Vis DRS spectroscopy. The degradation of reactive red (RR 120) under visible-light illumination were evaluated. The surface plasmon resonance (SPR) effect of Ag nanoparticles enhances the absorption and utilization of visible light. The Ag/Ag3PO4–BiOBr–C3N4 composite exhibited 92.6% degradation efficiency with the removal rate 0.042 min-1 which is 5.2, 2.7 and 2.5 times greater compared to pristine Ag/Ag3PO4, BiOBr and C3N4 particles. The active species holes (h+), superoxide (•O2–) and hydroxyl (•OH) radicals were responsible for the degradation process. The 4 times of cycle experiments proved the relatively high stability of the synthesized photocatalyst. The quaternary Ag/Ag3PO4–BiOBr–C3N4 heterojunction can endorse enhanced redox capability. The faster interfacial transport was validated, for quaternary photocatalysts using the EIS Nyquist plot. The work has driven a significant guidance in designing photocatalysts with surface plasmon effect.

Bryophyllum pinnatum leaf extract mediated ZnO nanoparticles with prodigious potential for solar driven photocatalytic degradation of industrial contaminants

In an era of environment-friendly development plant extract-based biological techniques for synthesizing nanoparticles have gained a lot of attention over traditionally famous chemical and physical synthesis techniques. In the present study we have synthesized biogenic zinc oxide nanoparticles (BPLE-ZnO NPs) using Bryophyllum pinnatum leaf extract, compared its native properties and solar-driven photocatalytic activity with chemically prepared ZnO nanoparticles (Chem-ZnO NPs). In order to characterize and compare the Chem-ZnO and BPLE-ZnO, various techniques were used, including UV–visible spectroscopy, x-ray diffractrometry, photoluminescence spectroscopy, field emission scanning electron microscopy, electron dispersive x-ray spectroscopy, fourier transform infrared spectroscopy, and zeta potential analyzer. The results revealed the formation of hexagonal wurtzite ZnO, with no significant difference between the two methods; however, the use of Bryophyllum pinnatum leaf extract in ZnO NPs synthesis resulted in reduced size, presence of biomolecules on its surface and better monodispersity than purely chemical synthesis. Further, the BPLE-ZnO NPs showed better efficiency in the solar-driven photocatalytic degradation of methylene blue (MB) dye compared to Chem-ZnO NPs. Under solar exposure at a dose of 0.50 mg/mL BPLE-ZnO, resulted in 97.31% photodegradation with a rate constant of 0.06 min−1 of 20 mg/L MB solution within just 60 min which was 9.51% higher compared to the Chem-ZnO NPs. The BPLE-ZnO NPs were also employed to investigate their solar-driven photocatalytic performance for degrading the pharmaceutical (Metronidazole and Amoxycillin) and textile pollutants (Methyl orange dye) under sunlight. The results show that Bryophyllum pinnatum leaf extract-mediated ZnO NPs have an excellent potential in solar-based photocatalytic applications.

Surface defect-induced electronic structures of lead-free Cs2AgBiBr6 double-perovskite for efficiently solar-driven photocatalytic performance

Lead-free Cs2AgBiBr6 double-perovskite has triggered appealing interest in various solar energy-related applications including solar devices and photocatalysis. Nevertheless, further development of the perovskite materials is restricted due to their low redox capacity of the energy band, which is determined by the intrinsic electronic structure. Herein, we demonstrate surface defect-induced electronic structures of the Cs2AgBiBr6 for achieving efficient photocatalytic performance by simply controlling the nucleation and growth processes of the lead-free double-perovskite. During the synthesis process, the strong interaction between the chelating agent EDTA and Cs+ ion leads to the generation of Cs vacancies of Cs2AgBiBr6, which promotes the formation of surface defects to control the electronic structure of double perovskite. The optimized Cs2AgBiBr6 has the strongest reduction capacity with the conduction band potential of −1.53 V (vs NHE at pH = 7) so far, which can greatly promote the production of superoxide radicals (O2–), improving the photocatalytic efficiency of the Cs2AgBiBr6. Under one simulated sunlight irradiation, the photodegradation efficiency of tetracycline (TC) for the as-obtained Cs2AgBiBr6 with surface defect is up to 81.8 % within 90 min. Environmental ImplicationEnvironmental pollution resulting from various factitious and industrial activities is primarily composed of organic compounds such as pesticides, dyes, antibiotic and so on. Antibiotic, difficult to decompose, can only be decomposed slowly by chemical or biological methods owing to their strong stability. Photocatalysis is emerging as a promising technology for environmental remediation because of its strong oxidation ability and fast reaction rate. The eco-friendly Cs2AgBiBr6 perovskite with a suitable bandgap (1.83 eV ∼ 2.19 eV) has recently emerged as a promising photocatalyst for application in pollutant degradation.

N-Rich Doped Anatase TiO2 with Smart Defect Engineering as Efficient Photocatalysts for Acetaldehyde Degradation.

Nitrogen (N) doping is an effective strategy for improving the solar-driven photocatalytic performance of anatase TiO2, but controllable methods for nitrogen-rich doping and associated defect engineering are highly desired. In this work, N-rich doped anatase TiO2 nanoparticles (4.2 at%) were successfully prepared via high-temperature nitridation based on thermally stable H3PO4-modified TiO2. Subsequently, the associated deep-energy-level defects such as oxygen vacancies and Ti3+ were successfully healed by smart photo-Fenton oxidation treatment. Under visible-light irradiation, the healed N-doped TiO2 exhibited a ~2-times higher activity of gas-phase acetaldehyde degradation than the non-treated one and even better than standard P25 TiO2 under UV-visible-light irradiation. The exceptional performance is attributed to the extended spectral response range from N-rich doping, the enhanced charge separation from hole capturing by N-doped species, and the healed defect levels with the proper thermodynamic ability for facilitating O2 reduction, depending on the results of ∙O2− radicals and defect measurement by electron spin resonance, X-ray photoelectron spectroscopy, atmosphere-controlled surface photovoltage spectra, etc. This work provides an easy and efficient strategy for the preparation of high-performance solar-driven TiO2 photocatalysts.

Rational construction of Ag3PO4/WO3 step-scheme heterojunction for enhanced solar-driven photocatalytic performance of O2 evolution and pollutant degradation

Heterojunction engineering has been regarded as a promising strategy to sufficiently utilizing photogenerated charge carriers, thus benefiting the improvement of photocatalytic performance. Herein, Ag3PO4/WO3 S-scheme heterojunction was synthesized via a simple deposition-precipitation process, and its photocatalytic activity was evaluated by monitoring water splitting and pollutant degradation under visible light. As a result, Ag3PO4/WO3 with optimized ratio photocatalyst showed enhanced photocatalytic activity in oxygen production (306.6 μmol·L-1·h−1) relative to pure Ag3PO4 (204.4 μmol·L-1·h−1). Additionally, it also exhibits rapid toxicity elimination efficiency over hexavalent chromium ions (Cr6+) and ciprofloxacin (CIP) with degrading rate of 72% and 83% within 30 min, respectively. According to a series characterization, a possible S-scheme photocatalytic mechanism of Ag3PO4/WO3 was demonstrated in detail, which endowed the heterojunction with strong redox abilities to provide powerful diving force towards the photocatalytic reaction. This work presents an innovative perspective to construct Ag3PO4-based S-scheme heterojunctions for boosting photocatalytic performance for various applications.

Planar heterojunction boosts solar-driven photocatalytic performance and stability of halide perovskite solar photocatalyst cell

The excellent optoelectronic properties of metal halide perovskites (MHPs) have been employed in various photocatalytic applications, but their poor water stability is considered as the main bottleneck for further development. Herein, we protect the light-absorbing CsPbBr3 MHP with a NiOx and TiO2 hole and electron extracting layer. This planar NiOx/CsPbBr3/TiO2 architecture can easily be fabricated through solution-processing. When applied to selective photocatalytic oxidation of benzyl alcohol, this system presents a 7-fold enhancement of photoactivity and an improved stability for over 90 h compared to CsPbBr3 counterpart. Interestingly, we find that trace amounts of water improve photoactivity. Through experimental and theoretical analyses, this improvement could be attributed to water-induced structural reorganization of MHP, leading to improved crystal quality and decreased effective masses of charge carriers. This work indicates planar heterojunction helps improve the photoactivity and stability of MHP photocatalyst, and our findings provide insights into the effect of water on MHPs.

Engineering surface oxygen vacancy of mesoporous CeO2 nanosheets assembled microspheres for boosting solar-driven photocatalytic performance

Surface oxygen vacancy defects of mesoporous CeO2 nanosheets assembled microspheres (D-CeO2) are engineered by polymer precipitation, hydrothermal and surface hydrogenation strategies. The resultant D-CeO2 with a main pore diameter of 9.3 nm has a large specific surface area (~102.3 m2/g) and high thermal stability. The mesoporous nanosheets assembled microsphere structure prevents the nanosheets from aggregation, which is beneficial to effective mass transfer and shortens the migration distance of charge carriers. After surface hydrogenation, the photoresponse extends to long wavelength region, combing with the band gap from 2.63 eV reduced to 2.39 eV. Under AM 1.5 G radiation, the photocatalytic degradation rate of tetracycline (TC) can be up to 99.99%, which is three times as high as that of pristine CeO2 microspheres. The excellent solar-driven photocatalytic performance can be attributed to the efficient surface oxygen vacancy engineering and the mesoporous nanosheets assembled microsphere structure, which narrows the band gap, shortens the migration distance of carriers, promotes the spatial separation of photogenerated electron-hole pairs and favors mass transfer. The strategy provides new insights for fabricating other high-efficient oxide photocatalysts .

Bridging role of Ag0 particles formed in-situ on Ag3PO4/BiPO4 composites for enhanced solar-driven photocatalytic performance

Ag3PO4/BiPO4 composite photocatalysts were constructed by a precipitation method. The composites were studied by Brunauer -Emmett-Teller (BET), X-ray diffraction patterns (XRD), UV-Vis diffuse reflectance spectra (DRS), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), surface photovoltage spectroscopy (SPS), electron spin-resonance (ESR) spectroscopy and X-ray photoelectron spectroscopy (XPS). Ag0 plays an important role in forming •O2 − and accelerating the separation of the photo-induced charge pairs, consequently the Ag3PO4/BiPO4 composites display high photocatalytic activity than the pure BiPO4 under simulated sunlight irradiation. The separation and transfer of the photo-induced charge pairs abide by a Z-scheme mechanism.

Enhanced solar-driven photocatalytic performance of a ternary composite of SnO2 quantum dots//AgVO3 nanoribbons//g-C3N4 nanosheets (0D/1D/2D) structures for hydrogen production and dye degradation.

Herein, we report the synthesis of between SnO2 QDs /AgVO3 nanoribbons/g-C3N4 nanosheets of ternary photocatalytic systems for the production of H2 through light irradiation. The SnO2/AgVO3/g-C3N4 photocatalyst was successfully produced by using the hydrothermal process. The structural characterizations of the samples revealed the successful formation of ternary heterostructures where SnO2, AgVO3 and g-C3N4 (quantum dots/nanoribbons/nanosheets) 0D/1D/2D structures make a good interface with each other. The fabricated heterostructures of AgVO3/g-C3N4 and SnO2/AgVO3/g-C3N4 photocatalytic structures performed enriched photocatalytic performance for H2 production over that of the pristine g-C3N4, AgVO3 and SnO2 photocatalysts. The AgVO3/g-C3N4 and SnO2 /AgVO3/g-C3N4 of photocatalysts were found to produce H2 of around 17,000 μmol g-1 and 77,000 μmol g-1, respectively, which is much 4.5 times greater than that of AgVO3/g-C3N4 photocatalyst. Moreover, the photodegradation behaviours of prepared catalysts were studied with the dye (rhodamine B, RhB) under light irradiation. The ternary composite SnO2/AgVO3/g-C3N4 performed photodegradation of RhB in 50 min. The higher photocatalytic activity for the ternary photocatalysts is predominantly due to the effective charge separation at the perfect interface formation amid SnO2 and AgVO3/g-C3N4.

Zinc sulfide quantum dots/zinc oxide nanospheres/bismuth-enriched bismuth oxyiodides as Z-scheme/type-II tandem heterojunctions for an efficient charge separation and boost solar-driven photocatalytic performance

A novel zinc sulfide quantum dot (ZnS QD)/zinc oxide (ZnO) nanosphere/bismuth-enriched bismuth oxyiodide (Bi4O5I2) tandem heterojunction photocatalyst is fabricated through two-step solvothermal, calcination and one-step hydrothermal strategies. The successfully constructed core-shell nanostructure can increase the interface area and the active sites of the composite photocatalysts. The formation of a Z-scheme/Type-II tandem heterojunction favors the transfer and spatial separation of charge carriers, in which Bi4O5I2 plays a bridging role to connect ZnO and ZnS. Simultaneously, the participation of Bi4O5I2 significantly shortens the band gap of the composite photocatalyst. This dual functional ZnO@Bi4O5I2/ZnS composite photocatalyst has a high photocatalytic hydrogen evolution rate of 578.4 µmol g−1h−1 and an excellent photocatalytic degradation efficiency for bisphenol A (BPA) and 2,4,5-trichlorophenol (TCP). In addition, cycling tests show that ZnO@Bi4O5I2/ZnS has a high stability, which is favorable for practical applications. This novel ZnO@Bi4O5I2/ZnS Z-scheme/Type-II tandem heterojunction photocatalyst will provide new ideas for the multichannel charge transfer of other highly efficient heterojunction photocatalysts.

Defect-rich and electron-rich mesoporous Ti-MOFs based NH2-MIL-125(Ti)@ZnIn2S4/CdS hierarchical tandem heterojunctions with improved charge separation and enhanced solar-driven photocatalytic performance

Defective-rich and electron-rich mesoporous NH2-MIL-125(Ti)@ZnIn2S4/CdS hierarchical tandem heterojunctions were fabricated through two-step solvothermal and one-step hydrothermal strategies. The interface with electron enrichment can cause active interface reaction, fast transfer and separation of charge carriers and restrain the photocorrosion of CdS. ZnIn2S4, as a bridge to connect Ti-MOFs and CdS, favors the separation of charge carriers and forms tandem heterojunctions. The as-prepared photocatalyst has a relative large surface area of ∼877.0 m2 g−1 and a narrow band gap of ∼1.84 eV, which could absorb visible light efficiently. Furthermore, it exhibits a high photocatalytic hydrogen generation rate which was increased to 2.367 mmol g−1 h−1 and the high photocatalytic degradation efficiency for 2,6-dichlorophen and 2,4,5-trichlorophenol which were 98.6% and 97.5%, respectively. Additionally, recycling text for several cycles indicates the high stability. This novel Ti-MOFs based core@shell hierarchical tandem heterojunctions may offer a new insight for fabricating high-performance heterojunctions for multi-channel charges transfer.

Promoted spatial charge separation of plasmon Ag and co-catalyst CoxP decorated mesoporous g-C3N4 nanosheet assembly for unexpected solar-driven photocatalytic performance

Plasmon Ag and co-catalyst CoxP decorated mesoporous graphite carbon nitride nanosheet assemblies have been synthesized via a template-calcination and ball milling strategy combined with photoreduction. The obtained composites are characterized by x-ray diffraction, Fourier transmission infrared spectroscopy, x-ray photoelectron spectroscopy, transmission electron microscopy, and UV–vis diffuse reflectance spectroscopy. The results show that the sample assembly with mesoporous structure has specific surface area of 50.4 m2 g−1, pore size of 11.3 nm and pore volume of 0.21 cm3 g−1. The Ag and CoxP nanoparticles are decorated on the surface of graphite carbon nitride uniformly. Under solar light irradiation, the photocatalytic degradation rate of ceftazidime for the prepared sample assembly is up to ∼92%, and the photocatalytic reaction rate constant is about 10 times higher than that of bare graphite carbon nitride. Moreover, the sample assembly also exhibits a solar-driven photocatalytic hydrogen production rate of 96.66 μmol g−1 h−1. It can attributed to the surface plasmon resonance effect of Ag nanoparticles and CoxP co-catalyst promoting the spatial charge separation and the mesoporous structure providing more surface active sites and favoring mass transfer. This special structure offers new insights for fabricating other high-performance photocatalysts with high spatial charge separation

Surface-oxygen vacancy defect-promoted electron-hole separation of defective tungsten trioxide ultrathin nanosheets and their enhanced solar-driven photocatalytic performance

Defective WO3 ultrathin surface-engineered nanosheets are fabricated by a solvothermal and low-temperature surface hydrogenation reduction strategy. The obtained defective WO3 ultrathin nanosheets with thicknesses of ∼4 nm possess a relatively large surface area of ∼25 m2 g−1. After surface engineering, the bandgap is narrowed to ∼2.48 eV due to the presence of surface oxygen vacancies, which further enhance the visible light absorption. The defective WO3 ultrathin nanosheets exhibit excellent solar-driven photocatalytic degradation performance for the complete degradation of the highly-toxic metribuzin herbicide (∼100%). The first-order rate constant (k) of the defective WO3 ultrathin nanosheets is ∼3 times higher than that of the pristine one. This can be ascribed to the formation of suitable surface-oxygen vacancy defects that promote the separation of photogenerated electron-hole pairs, and the two-dimensional ultrathin structure facilitating the surface engineering as well as furnishing a large number of surface active sites. Moreover, the defective WO3 ultrathin nanosheets exhibit high stability because the photocatalytic activity remains almost unchanged after 10 cycles, making them favorable for practical applications. This work offers new insights into the fabrication of other high-performance ultrathin nanosheet oxide photocatalysts for environmental applications.

Surface oxygen vacancy defect-promoted electron-hole separation for porous defective ZnO hexagonal plates and enhanced solar-driven photocatalytic performance

Porous defective ZnO cellular hexagonal plates with surface oxygen vacancies (OVZCHPs) are fabricated by hydrothermal and high-temperature NaBH4 reduction methods. The prepared OVZCHPs with a hexagonal structure have a relatively large specific surface area compared to that of pristine ZnO (ZCHPs), and the pore diameter is ~53.5 nm. After reduction, the defective OVZCHPs with a narrow band gap of ~2.95 eV extends the photoresponse to visible light region. Additionally, the surface oxygen vacancy defects are formed during the NaBH4 reduction procedure, which is confirmed by X-ray photoelectron spectroscopy, and favor the electron-hole separation. The solar-driven photocatalytic degradation rate of tetracycline for the OVZCHPs is up to ~99.9%, which is approximately three-times higher than that of the ZCHPs. This enhancement can be attributed to the hexagonal porous structure offering more surface active sites and the surface oxygen vacancy defects favoring the electron-hole separation and visible-light absorption. The novel OVZCHPs are promising photocatalysts for wastewater purification, and the fabrication strategy may provide new insights for designing other high-performance porous photocatalytic materials.

Enhancement of Photocatalytic Activity of Bi2 O3 -BiOI Composite Nanosheets through Vacancy Engineering.

Vacancy engineering is an effective strategy to enhance solar-driven photocatalytic performance of semiconductors. It is highly desirable to improve the photocatalytic performance of composite nanomaterials by the introduction of vacancies, but the role of vacancies and the heterostructure in the photocatalytic process is elusive to the composite nanomaterials. Herein, the introduction of I vacancies can significantly enhance the photocatalytic activity of Bi2 O3 -BiOI composite nanosheets in a synergistic manner. The excellent photocatalytic performance of the Bi2 O3 -BiOI composites is attributed to the combination of Bi2 O3 and BiOI and the existence of I vacancies in Bi2 O3 -BiOI composites. Specifically, density functional theory calculation shows that the existence of I vacancies would create a new electric states vacancy band below the conduction band of BiOI and thus can reduce the bandgap of BiOI nanosheets. This greatly facilitates the scavenging of the photogenerated electron on the surface of BiOI by Bi2 O3 , therefore, enhancing the overall photocatalytic activity of the composites. The enhanced photocatalytic efficiency is demonstrated by the degradation of tetracycline (TC), which reaches 96% after 180 min and by the high total organic carbon (TOC) removal (89% after 10 h visible light irradiation). This study provides a novel approach for the design of high-performance composite catalysts.

In-situ Platinum Plasmon Resonance Effect Prompt Titanium Dioxide Nanocube Photocatalytic Hydrogen Evolution.

Herein, Pt-decorated TiO2 nanocube hierarchy structure (Pt-TNCB) was fabricated by a facile solvothermal synthesis and in-situ photodeposition strategy. The Pt-TNCB exhibits an excellent solar-driven photocatalytic hydrogen evolution rate (337.84 μmol h-1 ), which is about 37 times higher than that of TNCB (9.19 μmol h-1 ). Interestingly, its photocatalytic property is still superior to TNCB with post modification Pt (1 wt %) (208.11 μmol h-1 ). The introduction of Pt efficiently extends the photoresponse of the composite material from UV to visible light region, simultaneously boosting their solar-driven photocatalytic performance, which attribute to the porous structure, the sub size TNCB, the SPR effect of Pt NPs and strong interaction of two components. In fact, Pt NPs can enhance collective oscillations on delocalized electrons, which is conducive to capture electrons and hinder the recombination of photogenerated electron-hole pairs, leading to the longer lifetime of photogenerated charges. The fabrication of Pt-TNCB photocatalyst with SPR effect may provide a promising method to improve visible-light photocatalytic activities for traditional photocatalysts.
